Introduction
Ethernet Base Controller Overview
The Ethernet Base Controller (EBC) provides a low-cost, high-performance
Ethernet link between a PC-based Control system, DL205 and DL405 I/O bases.
The EBC occupies the CPU position of the PLC base and communicates across the
backplane to input and output modules.
Although, the Ethernet Base Controller occupies the CPU slot in the PLC base, the
control function is not performed by the EBC. The control function is performed by
PC–based Control software (which is purchased separately) running on a PC. The
function of the EBC is to:
• process analog and digital input signals
• format the I/O signals to conform to the Ethernet standard
• transmit the signals to the PC-based controller
• receive and translate output signals from the PC-based Control software
• distribute the output signals to the appropriate output module in the
base
I/O Values Stored
in Cache Memory
The EBC module continually scans all I/O and stores the most recent values in
cache memory. The cache memory contents are available to the PC-based Control
software as a block of data or by individual slot location. The EBC reads all channels
of digital modules on each scan. It reads one channel of each analog module on
each scan, updating that value in cache memory. On the next scan, the EBC
sequences to the next channel and updates that value in cache memory, and so on.
Typically, PC-based Control will request all input and output values at the same time
from the EBC. The EBC passes the cache memory values for all channels of all input
and output modules. By using this method, very fast response times can be
achieved by the PC-based Control system.

H2–EBC and
H2–EBC–F
Introduction
The H2–EBC and H4–EBC modules support industry standard 10BaseT Ethernet
communications, and the H2–EBC–F and H4–EBC–F modules support 10BaseFL (fiber
optic) Ethernet standards. All EBCs offer 10Mbps transfer rates between your PC
application and your I/O base.
The H2–EBC(–F) installs in the CPU slot of a DL205 base and communicates across
the backplane to digital and analog input and output modules. The H2–EBC(–F)
does not support remote I/O or Specialty Modules.

Introduction
Frequently Asked Questions
Q. What is Ethernet?
A. Ethernet is a specification which defines cable type and signalling methods to be
used in a local-area-network (LAN). An Ethernet network transmits packets of
information between computers at speeds of 10 to 100 million bits per second
(Mbps). Currently the most widely used version of Ethernet technology is the 10Mbps
twisted-pair variety. Ethernet allows multi-vendor products to communicate using
common software protocols.
Q. Which protocols are supported by the EBC?
A. The H2–EBC(–F) and the H4–EBC(–F) support IPX (originated by Novell) and
UDP/IP (Universal Datagram Protocol/Internet Protocol). The Windows NTt
operating system supports both protocols. The UDP/IP protocol is supported within
the TCP/IP suite.
Q. What Ethernet standards should I be familiar with?
A. Below is a short list of most commonly used Ethernet cabling standards and their
key characteristics.
•
•
•
Installation and
Safety Guidelines
•
10Base-2 – Thin coaxial cable, which supports a maximum of 30
stations per network and is limited to 185 meters (607ft.) per cable
segment.
10Base-5 – Thick coaxial cable, which supports a maximum of 100
stations and is limited to 500 meters (1,640ft.) per segment.
10Base-F – Plastic or Glass Fiber Optic maximum of 1024 stations and
distances depend on signaling technology and medium used but can
commonly support up to 2 Kilometers.
10Base-T – Unshielded Twisted Pair, which supports a maximum of
1024 stations with a segments of 100 meters, but distance is truly based
on signal loss in decibels (less than 11.5dB loss source to destination).
Q. Which Ethernet specifications are required to install an EBC system?
A. None. Detailed Ethernet specifications are not necessary for implementing the
EBC system.
Q. How do I connect to an Ethernet network?
A. Different types of Ethernet media may be connected to a single LAN network
solution using repeaters, bridges, and adaptor type products. A number of vendors
offer adaptors or transceivers, which provide interconnection of different types of
Ethernet cabling.

Installation and Setup
Setting the Module ID
Each Ethernet Base Controller must have a Module ID in order to be recognized on
the network, and each Module ID must be unique. Duplicate Module IDs on the same
network will cause unpredictable results and must be avoided.
Installation and
Safety Guidelines
Installation
and Setup
Three Methods for
Setting Module ID
There are three methods for setting the Module ID, and they are the same for the
H2–EBC and the H4–EBC modules. You can set the Module ID using:
• The DIP switch on the EBC module
• The NetEdit software utility
• The software utility in your PC-based Control software (if a utility is
provided)
We recommend using the DIP switch to set the Module ID because the DIP switch is
simple to set, and the Module ID can be determined by looking at the physical
module, without reference to a software utility.
You can use the DIP switch to set the Module ID to a number from 1 – 63. Do not use
Module ID 0 for communications. The only pupose of Module ID 0 is to allow
communications with a PC while changing the Module ID.
If the DIP switch is set to a number greater than 0, the software tools are disabled
from setting the Module ID. Again, the software tools will only allow changes to the
Module ID if the DIP switch setting is 0 (all switches OFF).
The DIP switch settings are read only at powerup. You must cycle power if you
change the DIP switches.
Setting Module ID Software changes to the Module ID do not require cycling power. To set the Module
with Software Tool ID using one of the available software tools, do the following:
• Check to be sure all DIP switches are set to the off position,
Module ID = 0 (see page 2–3 or 2–4)
• Insert the module in the base (see page 2–5)
• Connect the power wiring (see page 2–6)
• Connect module to the Ethernet network (see page 2–8 through 2–10)
• Apply power
• Link to the module and change the Module ID using the software of your
choice. Remember to update the module before exiting the software.
See note below.
Setting Module ID
with DIP Switches
NOTE: Set the Module ID using the method recommended for your PC-based
Control software. The use of NetEdit to set the Module ID is described in Chapter 3.
Some PC-based Control software packages may make automatic updates to the
EBC module configuration, overwriting the configuration developed in NetEdit.

The H2–EBC DIP Switch
The H2–EBC (–F)
DIP Switch
The EBC DIP switch contains eight individual switches, but only six of these are
active. You will find that the printed circuit board is labeled 0 – 7. The numbers on the
printed circuit board indicate the power of 2 represented by each individual switch.
For example, switch 0 represents 20 (or 1), switch 1 is 21 (or 2), switch 2 is 22 (or 4),
and so on. The figure below shows the binary value of each switch in parentheses ( ).

Installation and
Safety Guidelines
The Module ID equals the sum of the binary values of the slide switches set in the ON
position. For example, if you set slide switches 1, 2, and 3 to the ON position, the
Module ID will be 14. This is found by adding 8+4+2=14. The maximum value you can
set on the DIP switch is 32+16+8+4+2+1=63. This is achieved by setting switches 0
through 5 to the ON position.

ID will be 10. This is found by adding 8+2=10. The maximum value you can set on the
DIP switch is 32+16+8+4+2+1=63. This is achieved by setting switches 0 through 5 to
the ON position. The DIP switch must be set to a number greater than zero.

DL205 Power Wiring and Grounding
Installation
and Setup
The power wires for the DL205 are not connected directly to the H2–EBC as they are
on the H4–EBC. The DL205 power supply is an integral part of the base and
separate from the EBC. The DL205 also has three power options: 12/24VDC,
125VDC, and 120/240VAC.
The diagram shows the terminal
connections located on the power supply
of the DL205 bases. The base terminals
can accept up to 16 AWG. You may be
able to use larger wiring depending on
the type of wire used, but 16 AWG is the
recommended size.
110/220 VAC Base Terminal Strip
NOTE: You can connect either a
120 VAC or 240 VAC supply to the AC
terminals. Special wiring or jumpers are
not required as with some of the other

H4–EBC Power Wiring and Grounding
Installation
and Setup
The power connection terminals are under the front cover of the Ethernet Base
Controller. The list below describes the function of each of the terminal screws.
• Relay – normally-open contact indicates that the EBC’s link to hub or
PC is good. Link Good indicator light is also on.
• 24VDC Auxiliary Power – can be used to power field devices or I/O
modules requiring external power. It supplies up to 400 mA of current at
20–28VDC, ripple less than 1 V P-P.
• Logic Ground – internal ground to the system which can be tied to field
devices or communication ports to unite ground signals.
• Chassis Ground – where earth ground is connected to the unit.
• AC Power –where the line (hot) and the neutral (common) connections
are made to the EBC.
• 110/220 Voltage Select – a jumper across two of the terminals
determines the voltage selection. Install the jumper to select 110VAC
input power, or remove the jumper to select 220VAC power input.
WARNING: Damage will occur to the power supply if 220 VAC is connected to the
terminal connections with the 115 VAC jumper installed. Once the power wiring is
connected, install the protective cover to avoid risk of accidental shock.
EBC Wiring
The following diagram shows the appropriate connections for each terminal. Note
that you should install a jumper between logic ground and chassis ground for best

10BaseT
The EBC has an eight-pin modular jack that accepts RJ45 connector plugs. UTP
(Unshielded Twisted-Pair) cable is rated according to its data-carrying ability
(bandwidth) and is given a category number. We strongly recommend using a
Category 5 (CAT5) cable for all Ethernet 10BaseT connections. For convenient and
reliable networking, we recommend that you purchase commercially manufactured
cables (cables with connectors already attached).
To connect an EBC (or PC) to a hub or repeater, use a patch cable (sometimes
called a straight-through cable). The cable used to connect a PC directly to an EBC
or to connect two hubs is referred to as a crossover cable.

Each module has two ST-style bayonet connectors. The ST-style connector uses a
quick release coupling which requires a quarter turn to engage or disengage. The
connectors provide mechanical and optical alignment of fibers.
Each cable segment requires two strands of fiber: one to transmit data and one to
receive data. The ST-style connectors are used to connect the H4–EBC–F module
to a PC or a fiber optic hub or repeater.

Calculating the Power Budget for the DL205 with H2–EBC
Managing your
Power Resource
When determining which I/O modules you will be using in the DL205 EBC system, it
is important to remember that there is a limited amount of power available from the
power supply. We have provided a table showing the power available from the
various DL205 base power supplies and a table showing the maximum power
consumed by the EBC and each of the I/O modules supported by the EBC. Following
these two tables is an example of a completed power budgeting worksheet and then
a blank worksheet you can use for your own calculations.
WARNING: It is extremely important to calculate the power budget. If you exceed
the power budget, the system may operate in an unpredictable manner which may
result in a risk of personal injury or equipment damage.
EBC Power
Specifications
Installation
and Setup
If the I/O modules you choose exceed the maximum power available from the
smaller DL205 base power supplies, you will need to use a D2–09B 9-slot base. This
base supplies more power than the other bases, as you can see in the table below.
The following table shows the amount of electrical current available at the two
voltages supplied from the DL205 base. Use these values when calculating the
power budget for you system.
The Auxiliary 24V power source mentioned in the table is available at the base
terminal strip. You can connect to external devices or DL205 I/O modules that
require 24VDC, but be sure not to exceed the maximum current supplied.

DL405 Local and Expansion I/O
The H4–EBC supports the use of DL405 series I/O local and local expansion bases.
Local Base and I/O The local base is the base in which the
EBC resides. Local I/O modules reside in
the same base as the EBC. For example,
placing 32-point modules in all eight slots
in an 8-slot base will use 256 I/O points .

Use local expansion bases when you need more I/O points or a greater power
budget than the local base provides. The expansion bases require a Local
Expansion Unit (rather than an EBC) and a cable (either D4–EXCBL–1 or
D4–EXCBL–2) to connect to the local EBC base.
The following figure shows one EBC base and three expansion bases. The I/O
modules are shown as examples of a usable configuration, but any configuration of
I/O modules could be used if it is supported by the power budget. See page 2–15 for
information about calculating the power budget.
The H4–EBC supports one local base and a maximum of three expansion bases.

NOTE: Your PC-based Control software may be capable of configuring the EBC
module. If so, please refer to the appropriate documentation for that software
product to determine the best method to configure the EBC. The use of Think & Do
software to configure the EBC is discussed in Appendices B and C of this manual.
Ethernet
Communication
Protocol
Some PC-based control software
products may support only one of
these
protocols.
Read
the
documentation for your software to be
sure the protocol you select is
supported.
NOTE: We strongly recommend you load IPX protocol on your PC and use it for your
PLC links. Use UDP/IP in your application, if required, but also add IPX to your list of
active protocols. Having IPX loaded on your PC gives you a backup for
troubleshooting communication problems.
Installation and
Safety Guidelines
The figure to the right shows the
Protocol selection box in the upper left
corner of the NetEdit screen. The
choice you make here tells your PC
which protocol to send to the EBC to
link NetEdit to the module. You are not
selecting which protocol the EBC
understands. It understands both.
Using
NetEdit
In the upper left corner of the NetEdit screen, you will find a box labeled Protocol. In
the box, there are two choices: IPX and UDP/IP. The EBC module understands IPX
and UDP/IP protocols. Both protocols are permanently resident in the firmware of
the module.
When you click on one of these radio buttons, you are selecting the protocol you
want your PC to use to communicate with the EBC module. You are not telling the
module which protocol to use, because it is using both protocols all the time. IPX is a
Novell standard in widespread use, and UDP/IP is a popular protocol supported by
the TCP/IP suite of protocols in your PC.

Adding Network
Protocol Support
to Your PC
You may have already set up your PC with selected networking protocols for
Ethernet communications. If not, you will need to select the protocols now for
communication with the EBC module. We strongly recommend that you include the
IPX protocol. From My Computer on your PC Desktop, go to Control Panel. Double
click on Network, then click on the Protocols tab. If IPX is not listed among the
protocols already loaded, add it now by clicking on the Add... button. The Select

Troubleshooting Guidelines
Isolating a Communication Problem
If you are experiencing a problem communicating with an EBC module, the problem
can usually be isolated to one of four components of the communication link:
• the EBC module itself (hardware or firmware)
• the communication program or the setup of the EBC module
• the cabling and connections
• other external influences, such as electrical noise, heavy communication
traffic on the network or exceeding the PLC power budget
Diagnostic Tools
and Techniques
Several available tools and techniques can help you isolate a communication
problem:
• The LEDs on the face of the module indicate the status of the link, the
module, and the network communications.
• Replacing the module may determine whether the problem is in the
module.
• NetEdit displays a list of the active modules on the network and their
protocol and configuration settings.
• Cable testing devices can pinpoint short or open circuits or diagnose
attenuation problems and other cabling problems.
• Diagnostic tools within your PC-based Control software.
Troubleshooting Chart

The following chart summarizes the different types of communication failures you
could experience. In each case the CPU PWR LED must be on, and you must be

The green LINKGD (LINK GOOD) LED is on steady when the EBC module is
connected properly to an active device on the network and is receiving 5VDC
operating voltage from the PLC power supply. The LINKGD LED verifies that the
proper cables are connected, and the EBC module is functioning correctly. If a
mismatch with the 10BaseT or 10BaseFL connections occurs this LED will not be
illuminated.
Troubleshooting
Guidelines
ACTIVITY Indicator The red ACT (ACTIVITY) LED flashes to indicate that the module is detecting data
on the network. If any network device is sending or receiving data, the ACT LED will
be illuminated. In idle mode (no network traffic) this LED is OFF. During heavy
communication loads this LED will be on steady.
ERROR Indicator
If the EBC module’s red ERROR indicator is flashing or on steady, a fatal error has
occurred. The error may be in the EBC module itself, or a network problem may be
causing this symptom. The ERROR indication can be caused by a faulty ground, an
electrical spike or other types of electrical disturbances. Cycle power to the system
to attempt clearing the error.

Using NetEdit for Troubleshooting
NetEdit is a software utility which came with this manual. To review the procedures
for running and using NetEdit, see Chapter 3. NetEdit allows you to:
• See active modules on the network.
• Examine and change the modules’ configuration settings.
• See the firmware revision number.
• Review statistical information about communication errors by type.
Select a Module
The Module box shows the Ethernet
Addresses of all modules which are
currently linked to the NetEdit utility. If your
EBC module is not on this list, try the
following:
•
Change Protocol selection and click on

devices are trying to communicate at the same time.
Lost Packets – packets that overflow the queue.
Bad Packets – packets that fit the Ethernet standard but are not in the
right format for the EBC module.
Unknown Type – a foreign command was received and could not be
interpreted. This will probably happen only during software driver
development.
Send Errors – the Ethernet standard number of retries were attempted
for a transmission.
Replacing the EBC If you are replacing an existing EBC module with a new one, you need to set up the
new module with the same Module ID as the module you are replacing. If you used
Module
the DIP switch to set the Module ID, you will need to set the DIP switch on the
replacement module to the same Module ID. See page 2–3 or 2–4 to review the
procedure for setting the Module ID using the DIP switch.
If you set up your original EBC module using NetEdit, you will need to duplicate the
settings in the new module using the same procedures. See page 3–2 through 3–7
to review the procedures for using NetEdit.
If you set up your original EBC module using your PC-based Control software, you
will need to refer to the appropriate documentation.
WARNING: Your system can be damaged if you install or remove system
components before disconnecting the system power. To minimize the risk of
equipment damage, electrical shock, or personal injury, always disconnect the
system power before installing or removing any system component.
Troubleshooting Guidelines
4–7
Diagnosing Network Cable Problems
If you are experiencing communication problems, swapping cables is one of the
simplest diagnostic procedures you can perform. If the network operates correctly
with a different cable, you have isolated and cured the problem. If possible, use a
short run of cable to test the network because problems with longer cable runs can
be more difficult to diagnose and are more often intermittent.
If you are unable to swap cables, verify the proper operation of all other network
components. You probably have a cable problem if you have verified that your:
• EBC module is working correctly.
• EBC module configuration is correct.
• RLL program or PC program is correct.
• hubs are working correctly.
• Windows configuration is correct.
• network adapter card is the correct type, and it is working correctly.
NOTE: Any significant difference between the cable characteristics of the
transmitter and receiver can cause communication errors.
Ethernet devices continually monitor the “receive data” path for activity as a means
of verifying their link is working correctly. When the network is idle, each network
device (including the EBC module) sends a periodic link test signal to verify that the
network is working. If the link test signal or other network activity is not received
periodically, the Link Good LED on the EBC module is turned off.
Troubleshooting
Guidelines
It is a good maintenance practice to test network cables periodically and maintain a
permanent record of cable characteristics. A number of cable test instruments are
available to test 10BaseT and 10BaseFL networks. These instruments will check the
electrical or optical characteristics of your cabling, including:
• Continuity – This is a check to make sure the communication pairs are
wired correctly, and that the wires are continuous from end to end. In the
case of fiber optic network this is a test to be sure light is transmitted
from one end of the cable to the other.
• Attenuation – This refers to the amount of signal loss over the cable
segment at the signal frequency of interest. The 10BaseT specification
allows for a maximum signal loss of 11.5 decibels (dB) for the entire link
at the signal frequency used by 10Mbps Ethernet. The 10BaseFL
specification calls for the optical loss in link segment to be no greater
than 12.5 dB.
• Crosstalk – Crosstalk occurs when a signal in one pair of wires is
electromagnetically coupled to an adjacent pair. This is critical
for10BaseT networks which are susceptible to noise interference.
10BaseFL networks are virtually immune to noise interference.

Installation and
Safety Guidelines
Appendix C
Using H4–EBC with T&D
Configuring the base is a necessary step in the setup of the H4–EBC module. The
H4–EBC must know the type and location of each input and output module installed
in the base. Once identified, the configuration resides in non-volatile memory
on-board the EBC until a change is made.
The H4–EBC is partially self-configuring. On powerup, the H4–EBC reads the base
to determine the specifications of installed modules. The information available
allows the H4–EBC to determine:
• whether the I/O modules are inputs or outputs
• whether the installed modules are standard I/O modules or a High
Speed Counter module (other intelligent modules are not supported at
this time)
If you are not using analog inputs or outputs the H4–EBC configures itself. For the
following module types, the DL405 I/O system provides the necessary configuration
information to the H4–EBC, and the H4–EBC automatically configures the base:
• digital inputs
• digital outputs
• High Speed Counter module
If you are using analog inputs or outputs you must configure the base manually
using a software utility imbedded in Think & Do:
You are ready to configure your base if you have done all of the following:
• installed your H4–EBC or H4–EBC–F module
• connected power wiring to the EBC terminal strip
• installed I/O modules and expansion bases as necessary for your
application
• connected your PC and EBCs to a dedicated Ethernet network
• installed Think & Do (Version 4.4, or later) on your PC
NOTE: The pages that follow explain how to use the Think & Do software utility for
configuring the base. For additional information about using the Think & Do software
product, please refer to the Think & Do Software Learning Guide.

Introduction to KEPServerEX
Introduction
to OPC
OPC, OLE (Object Linking and Embedding) for Process Control, is an industry
standard created by a number of worldwide leading hardware and software
suppliers in cooperation with Microsoft. The OPC Data Access specification, as
maintained by the OPC Foundation, is a non–proprietary technical specification that
defines a set of standard interfaces based upon Microsoft’s OLE/COM technology.
An OPC server (driver) allows items such as distributed control systems,
programmable logic controllers, I/O systems and smart field devices to
communicate with a wide range of HMI/SCADA (client) software packages residing
on a PC. Traditionally, each software or application developer was required to write a
custom interface, or server/driver, to exchange information with hardware field
devices. OPC eliminates this requirement allowing manufacturing customers true
plug and play connectivity and the freedom to choose products based on their
automation requirements.
DDE Support
While KEPServerEX is first and foremost an OPC server, KEPware recognized that
a number of legacy applications still depend upon DDE for their underlying client
server technology. Early in the development of Windows, Microsoft provided a
generic client server technology called DDE (Dynamic Data Exchange). DDE did
provide a basic architecture that would allow many windows applications from a
wide range of vendors to share data. But there was one problem, DDE was not
designed for the industrial market lacking much of the speed and robustness desired
in an industrial setting. However, this did not stop DDE from becoming a dominant
client/server architecture, largely due to its availability in most windows applications.
KEPServerEX
KEPServerEX Enhanced OPC/DDE Server is a 32 bit windows application that
provides a means of bringing data and information from a wide range of industrial
devices and systems into client applications on your Windows PC. KEPServerEX
falls under the category of a ”Server” application. It is very common to hear the term
”client/server application” in use across many software disciplines and business
segments. In the industrial market, it has usually come to mean the sharing of
manufacturing or production data between a variety of applications ranging from
human machine interface software and data historians, to large MES and ERP
applications.
At a high level, the KEPServerEX OPC Server is comprised of several objects that
are described on the next page.
Channel Object
Device Object
Group Object
Tag Object
Using H2–EBC with KEPware OPC Server
D–3
Channel Object: Each protocol or driver used in a KEPServerEX project is referred
to as a channel. A channel refers to a specific communications driver. A
KEPServerEX project can consist of many channels each with unique
communications drivers or each with the same communications driver.
Each channel name must be unique in a KEPServerEX application. The channel
name entered here will be part of the OPC browser information.
Device Object: Unlike the channel name, ”Device names” can be the same from
one channel to the next. The device name is a user defined logical name for the
device. The device name and channel name will be part of the OPC browser
information as well as a DDE item name. Within an OPC client the combination of
channel name and device name would appear ”ChannelName.DeviceName”.
Group Object: KEPServerEX allows tag groups to be added to your project. Tag
groups allow you to tailor the layout of OPC data in logical groupings that fit the
needs of your application. Using tag groups allows multiple sets of identical tags to
be added under the same device. This can be very convenient when a single device
handles a number of similar machine segments. From an OPC client standpoint, the
use of tag grouping allows you to segregate your OPC data into smaller tag lists,
which can make finding a specific tag easier when browsing the server.
Tag Object: KEPServerEX allows both dynamic tags, (tag entered directly at the
OPC client that specify device data) and user defined tags. User defined tags have
the benefit of allowing the tag to be browsed from an OPC client that supports tag
browsing. User defined tags also support tag scaling. Unlike many of the dialogs you
will find in KEPServerEX, the tag properties dialog has a number of features that are
driven by icons. The tag name is part of the OPC browse data. Tag names must be
unique within a given device branch or tag group branch. If your application is best
suited by using blocks of tags with the same names, use tag groups to segregate the
tags.

KEPServerEX Project: Adding and Configuring a Channel
Running the Server KEPServerEX, like any OPC server, can be started a number of ways. One of the
benefits of OPC technology is that your OPC client can automatically invoke the
server when it attempts to connect and collect data from it. In order for this automatic
mode of operation to occur you must first create and configure a project. Once you
have created a project, KEPServerEX will automatically select the most recently
used project when it is invoked by an OPC client.
Initially however, you need to manually invoke KEPServerEX using either the
desktop icon, if you chose to install it, or by selecting KEPServerEX from the
windows start menu. Depending on any changes you may have made to the
appearance of KEPServerEX, once invoked you should be presented with the
following interface. To learn more about the various elements of the user interface
see (Basic KEPServerEX Components).
While discussing how to start KEPServerEX its important to understand what the
system requirements are for running the server. KEPServerEX has been designed
to place as little strain on your system as possible.
Recommended System Requirements:
400Mhz Pentium
64 Megs of Ram
10 Megs of Hard Disk Space
Windows NT(SP6a)/2000 (Strongly recommended for industrial settings)
Available Ethernet Card

H2–EBC/KEPware OPC
Adding a Channel
A channel refers to a specific communications driver. A KEPServerEX project can
consist of many channels each with unique communications drivers or each with the
same communications driver. Depending on the driver or drivers you have installed
you can define a number of channels within a single project. A channel acts as the
basic building block of an OPC link. Properties like communications port, baud rate,
and parity are contained at the channel level. Each channel name must be unique in
a KEPServerEX project. The channel name can be up to 31 characters long.
To add a new channel to your project you can use the Edit menu > New Channel, the
Toolbar Add Channel, or the “Click to add a channel” dialog.
Using H2–EBC with KEPware OPC Server
Selecting the
Device Driver
D–5
Select the device driver you want to assign to the channel. A driver list will be
presented displaying all of the device drivers that are installed in your system.
Selecting the ”Enable diagnostics” check box will enable diagnostic information to
be available to your OPC application for this channel. With diagnostic functions
enabled, diagnostic tags are available for use within client applications. In addition
to diagnostic tags, a diagnostic window is also available when this feature is
enabled. The diagnostic features of KEPServerEX do require a minimal amount of
overhead processing. For this reason it is recommended that you only use the
diagnostic features when needed and disable them when not in use which is the
default case.
Selecting the
Network Adapter
Appendix D
H2–EBC/KEPware OPC
The Network Interface selection allows you to select a specific NIC card for the
Automationdirect EBC Ethernet driver to use based on the NIC name or its assigned
IP address. By selecting a specific NIC interface you will be able to force the driver to
send all Ethernet communication through the specified NIC. If you do not know
which NIC you should use, select the ”Default” condition.

Using H2–EBC with KEPware OPC Server
Setting the
Server Writes
Optimizations
As with any OPC server, writing data to your device may be the most important
aspect of your application. Insuring that the data written from your OPC client
application gets to the device in a timely manners is the goal of the server.
KEPServerEX provides a number of optimization settings that can be used to tailor
the server to meet the needs, and improve the responsiveness of your application.
There are currently three write optimization modes. The following is a brief
description of the modes. For a detailed explanation, refer to the “Channel
Properties – Write Optimizations” section in the KEPServerEX on–line help file.
NOTE: We strongly suggest that you characterize your application for
compatibility with these write optimization enhancements before using them
in a production environment.
Appendix D
H2–EBC/KEPware OPC
The default mode, ”Write all values for all tags” will force the server to attempt to
write every value to the controller. This mode insures that everything written from
your OPC client applications will be sent to the target device. While writing every
value to the device may seem like the best course of action, there are a number of
applications where writing every value, many of which may be the same value, over
and over may be simply a waste of communications bandwidth.
The ”Write only latest value for non–boolean tags” allows any value that is not a
boolean value to be updated in the server’s internal write queue and will then be sent
to the device at the next possible opportunity. This can dramatically improve the
overall performance of your application. This feature must be used with a clear
understanding of how it will affect the operation of your application.
The final write optimization mode, ”Write only the latest value for all tags”, takes
the operation described for the second mode and applies it to all tags.
The Duty Cycle selection allows you to control the ratio of write operations to read
operations. By default the duty cycle is set to ten. This means that ten writes will
occur for each read operation. If your application is doing a large number of
continuous writes but you need to insure that read data is still given time to process,
you may want to reduce the Duty Cycle. A setting of one will result in one read
operation for every write operation. In all cases if there are no write operations to
perform, reads will be processed continuously.

With Channel1 added to the server, the KEPServerEX window will appear as
follows:
Note that the channel is shown using the channel name given, but it also has a small
red ”x” below the channel icon. The red ”x” indicates that the channel does not
contain a valid configuration. Channel1 is not valid because a device has not yet
been added to the channel.
Using Multiple
Channels in a
Project
Appendix D
H2–EBC/KEPware OPC
KEPServerEX supports the use of multiple channels. As you add channels to your
project you can specify either the same communications driver or different
communications drivers. Most communication drivers offered by KEPware support
operation on up to 16 communications ports or ethernet network connections
simultaneously. By defining multiple channels you can improve the overall
performance of you application. In the case of either a serial driver or Ethernet driver
using multiple channels allows you to spread large communications loads across
the multiple channels. A good example of this would be a serial driver that is being
used to communicate with eight devices on the serial line. Normally the
communications driver used in this application would be responsible for gathering
data from all eight devices in a round robin fashion. If this same application is
reconfigured to use multiple channels assigned to multiple communications ports,
the device load can be divided across the channels. The end result is reduce work
load on each channel and dramatic improvements in the responsiveness of your
application. The need to use multiple channels is dependent solely on the needs of
your application. In either case there is no additional cost involved to use a licensed
driver on multiple communications or Ethernet ports.

KEPServerEX Project: Adding and Configuring a Device
Adding a Device
Once a channel has been configured in a KEPServerEX project, a device must be
added to the channel. Devices represent PLCs, I/O devices or other hardware that
the server will communicate with. Device selection is restricted by the device driver
the channel is using.
To add a device to a channel, select the desired channel and use the Edit menu >
New Device, the Toolbar Add Device, or the “Click to add a device” dialog.
Selecting the
Device Model
The ”Model” parameter allows you to select the specific type of the device
associated with a device ID. The contents of the model selection drop down will vary
depending on the chosen communication driver.

Selecting the
Device Model
D–9
The ”Device ID” parameter allows you to specify the driver specific station or node
address for a given device. Since the Automationdirect EBC driver is an Ethernet
based driver, a unique and valid TCP/IP address must be entered. IPX protocol is not
supported.
Setting the Device Device timeout parameters allow a driver’s response to error conditions to be
Timeout Properties tailored to the needs of your application. The timeout parameters are specific to each
device you configure. Each of the field parameters is defined in detail in the “Device
Properties – Timeout” section in the KEPServerEX on–line help file.
Appendix D
H2–EBC/KEPware OPC
The Connection timeout: allows the time required to establish a socket connection
to a remote device to be adjusted. The Request timeout: is used by all drivers to
determine how long the driver will wait for a response from the target device. The
Fail after parameter is used to determine how many times the driver will retry a
communications request before considering the request to have failed. If your
environment is prone to noise induced communications failures you may want to
increase the number of retries the driver performs.

Automatic OPC
Tag Database
Generation
The automatic OPC tag database generation features of KEPServerEX have been
designed to make the setup of your OPC application a Plug and Play operation.
Since the Automationdirect EBC communication driver supports this feature, you
can configure it automatically build a list of OPC tags within KEPServerEX that
correspond to device specific data. The automatically generated OPC tags are then
browsable from your OPC client. The OPC tags that are generated are dependent
upon the nature of the supporting driver. Each field selection is defined in detail in the
“Automated OPC Tag Base Generation” section in the KEPServerEX on–line help
file.
The ”Automatic tag database generation on device startup” selection allows you
to configure when OPC tags will be automatically generated. There are three
possible selections. The default condition, ”Do not generate on startup”, will
prevent the driver from adding any OPC tags to tag space of KEPServerEX. The
selection ”Always generate on startup”, will cause the driver to always evaluate
the device for tag information and to add OPC tags to the tag space of the server
each time the server is launched. The final selection ”Generate on first startup” will
cause the driver to evaluate the target device for tag information the first time this
KEPServerEX project is run and to add any OPC tags to the server tag space as
needed. When the automatic generation of OPC tags is selected, any tags that are
added to the server’s tag space must be saved with the project. You can configure
your KEPServerEX project to auto save from the Tools > Options menu.

D–11
KEPServerEX Project: Adding Tags to the Project
There are two ways to get data from a device to your client application using
KEPServerEX. The first method, and most common method, of defining tags is
called User Defined Tags. This requires that you define a set of tags in the server
project and then use the name you assigned to each tag as the item of each
OPC/DDE link between the client and the server. The primary benefit to this method
is that all user defined tags are available for browsing within OPC clients.
Additionally, user defined tags also support scaling.
The second method of defining tags is called Dynamic Tags. Dynamic tags allow
you to define tags in the client application. Instead of providing the server with a tag
name as the OPC/DDE item, you would provide the device address (and optionally a
data type). The server will create a tag for that location and start scanning for data
automatically. KEPServerEX allows tag groups to be added to your project.
Tag groups allow you to tailor the layout of OPC data in logical groupings that will fit
the needs of your application. Using tag groups allows multiple sets of identical tags
to be added under the same device. This can be very convenient when a single
device handles a number of similar machine segments. From an OPC client
standpoint, the use of tag grouping allows you to segregate your OPC data into
smaller tag lists, which can make finding a specific tag easier when browsing the
server.
User Defined Tags
Each field selection is defined in detail in the Tag Properties section in the
KEPServerEX on–line help file. A brief description of each is listed below.
Appendix D
H2–EBC/KEPware OPC
The tag Name: parameter allows you to enter the string that will represent the data
available from this tag. The tag name can be up to 31 characters in length. While
using long descriptive names is generally a good idea, keep in mind that some OPC
client applications may have a limited display window when browsing the tag space
of an OPC server. The tag name is part of the OPC browse data. Tag names must be
unique within a given device branch or a tag group branch. If your application is best
suited by using blocks of tags with the same names, use tag groups to segregate the
tags.
Appendix A
D–12
Using H2–EBC with KEPware OPC Server
The Address: parameter allows you to enter the desired driver address for this tag.
To determine how an address should be entered, you can use the Hints button next
to the address parameter. Hints provide a quick reference guide to the address
format of the driver. Once you have entered an address you can test it by using the
check address button. When pressed, the check address button attempts to validate
the address with the driver. If the driver accepts the address as entered no message
will be displayed. If an error is detected a pop–up will inform you of the error. Keep in
mind that some errors will be related to the data type selection and not the address
string.
The Description: parameter allows you to attach a comment to this tag. A string of
up to 64 characters can be entered for the description. If you are using an OPC client
that supports Data Access 2.0 Tag Properties, the description parameter will be
accessible from the Item Description property of the tag.
Appendix D
H2–EBC/KEPware OPC
The Data Type: selection allows you to specify the format of the tag’s data as it is
found in the physical device. The data type setting is an important part of how a
communication driver reads and writes data to a device. For many drivers the data
type of a particular piece of data is rigidly fixed.
The available data type selections are:
S
Default – This type allows the driver to choose its default data type see the
specific driver help for details
S
S
Boolean – Single bit data On or Off
Char – Signed 8 bit data
S
Byte – Unsigned 8 bit data

Double – 64 bit Real value IEEE format
S

BCD – Two byte packed BCD value range is 0 – 9999
LBCD – Four byte packed BCD value range is 0 – 99999999
The Client access: selection allows you to specify whether this tag is Read Only or
Read/Write. By selecting Read Only you can prevent client applications from
changing the data contained in this tag. By selecting Read/Write you are allowing
client applications to change this tag’s value as needed.
The DDE scan rate: parameter allows you to specify the the update interval for this
tag when used in a DDE client. OPC clients can control the rate at which data is
scanned by using the update rate that is part of all OPC groups.
The Do not allow client to override data type selection allows you force OPC
clients to use the data type you have specified for this tag. OPC clients can specify
how they desire to view the data from a particular tag.

Using the RJ12 Serial Port in ASCII Mode
The H24–EBC RJ12 serial port can be configured for generic ASCII
communications (refer to the “Advanced Settings” section in Chapter 3 to confirm or
change the RJ12 serial port settings). Both the transmit buffer and receive buffer of
the driver are 127 bytes in size. Thus, the corresponding tags can be a maximum of
127 bytes. Incoming bytes are appended to the receive buffer.
Port specifiers precede the serial port address. It defines which port the serial port
address corresponds to. To define an EBC address the mnemonic EBC is used and
the mnemonic SP0 specifies serial port 0. For addressing the EBC serial port, no
base or slot information is needed.
As shown below in the Hints dialog, there are several port address parameters. In
many cases the default values can be used. A detailed list explaining the parameters
are found by clicking on the Help button in the Hints window. Then click on the Index
button in the Terminator I/O, I/O Addressing window. Then locate the “H2, H4,
